Figure C-2. Common Command Syntax Diagram
Figure C-3 is a tree diagram of the subsystem commands. Commands starting at the root direction are listed as either single
commands or command subsystems. Command subsystems may consist of a single command, but usually are comprised of a
set of commands that extend two or more levels below the root. Commands followed by a question mark (?) take only the
query form. Except as noted in the syntax descriptions, all other commands take both command and the query form.
